How to Buy an Arduino Leonardo (Clone) Kit for Less than $20

Borderless Electronics Indiegogo campaign for their $9 electronics kit with an Arduino Leonardo clone went so well that the owner of the campaign decided to limit the total number of boards to 15,000, and basically stop the campaign early to avoid production delays. For $12 ($9 + shipping), you could get a full kit with: Arduino Leonardo clone A mini breadboard with 10 Jumper wires A plug for a 9V battery A few components: 6 LEDs, 10x 330 Ohm resistors, 10x 1 KOhm resistors, 3x push buttons, 2 NPN transistors, 5 diodes, a light sensor, and a sound buzzer A micro USB to USB cable Although they may start a new one campaign in a few months, the campaign is over, and you can’t get this cheap Arduino kit anymore. But one of my reader (onebir) let me know that for less than $20, you can  get an Arduino Leonardo […]

Borderless Electronics Sells $9 Arduino Compatible Starter Kit

The Raspberry Pi fundation, a nonprofit organization, has brought a low cost ARM Linux platform to the masses, and Arduino already did that with electronics, but Harold Timmis, an engineer, found out it was still not cheap enough as he worked as a volunteer teaching electronics at his library. So he (and others) decided to clone Arduino Leonardo, setup a website called Borderless Electronics, and sell it without profit via Indiegogo for just $9 ($12 including shipping). The board is indeed the same as Arduino Leonardo with different color, logo, and name: Microcontroller – Atmel ATmega32u4 @ 16 MHz SRAM – 2.5 KB onchip (ATmega32u4) Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader EEPROM – 1 KB onchip (ATmega32u4) Operating Voltage – 5V Input Voltage – (recommended) 7-12V | (limits) 6-20V Digital I/O – 20 pins PWM – 7 channels Analog Input – 12 […]

Beyond Semiconductor Announces BA21 Processor Core for Embedded MCUs

Beyond Semiconductor, a Ljubljana, Slovenia based company, has recently announced BA21, a 32-bit processor core, with 2.5 Coremark per megahertz, and clocked up to 125 MHz, that’s roughly equivalent to a Cortex M3 core @ 120 MHz. Target applications include mixed signal embedded processing, wireless communications ICs (e.g. Bluetooth, Zigbee, GPS), industrial Microcontrollers, and battery-powered or ultra-low-cost devices.If you’ve never heard about Beyond Semi, you may want to read my previous article about their BA25 core (Cortex A7/A8 equivalent) for a bit more details about the company. Here are the key features of BA21 core: 32-bit Processor Small silicon footprint (less than 10k gates) for lower leakage and dynamic CPU power Two-stage pipeline architecture Extreme Code Density for lower instruction fetching energy Advanced power management Dynamic clock gating and power shut-off of unused units Software- and hardware-controlled clock frequency Wake-up on tick timer or external interrupt Performance Up to 2.5 […]
